I can not bind the value ? Help me

var fs = require("fs");

function mergeValues(values, content) {
  //Cycle over the keys
  for(let key in values) {
    //Replace all {{key}} with the value from the values object
    content = content.replace(`{{${key}}}`, values[key]);
  }
  //return merged content
  return content;
}

function view(templateName, values, response) {
  //Read from the template file
  var fileContents = fs.readFileSync('././view/' + templateName + '.html', {encoding: "utf8"});
  //Insert values in to the content
  fileContents = mergeValues(values, fileContents);
  //Write out the contents to the response
  response.write(fileContents);
}

module.exports.view = view;
